If $${x^2y\over z} = 24$$ and $${y^4z\over x} = 30$$, find the value of $$x^2 \over (yz)^5$$

I think the way to go for this problem is to substitute in a few values in terms of other variables.

I multiplied equations 1 and 2 to get $${x^2y^5z\over{xz}}=720$$.

Thus, $$xy^5 = 720$$.

Not quite sure what to do from here, maybe you can give it a go Guest! (try substituting in variables in terms of other variables, and try plugging it into the expression)

Good luck :D!
